title: Eosinophilic enteritis: a rare cause of diarrhoea.
abstract: We report a case of a healthy young man presenting with 1-week history of diarrhoea, acute abdominal pain and weight loss. Laboratory investigation showed very high peripheral eosinophils levels. After exclusion of the other causes of eosinophilia, a histological bowel sample analysis revealed marked eosinophilic infiltration of a small bowel mucosal layer which confirmed the suspicion of eosinophilic enteritis. Unlike most of the described cases, this patient did not require any specific treatment. Eosinophilic gastroenteritis is a rare and heterogeneous disease that is probably underdiagnosed in clinical practice because it requires a high degree of suspicion and an endoscopic biopsy for definite diagnosis.
